IMPROVED APPARATUS FOR TREATING PETROLEUM.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, ALEXIS' THIRAULT, of ll illiomsburg, in the county of Kings, and State of New York, linvc invented a. new and improved Apparatus for Treating Petroleum; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the some, reference being had to the nccompunying drawings, forming part of this specification, in which Figure 1 represents a longitudinal vertical section of this invention, the line roar, fig. 3, indicating the plane of section.

Figure 2 is a side elevation of the some.

Figure 3 is a. plan or top view of the some.

Similar letters of reference indicate like ports.

This invention relates to an apparatus which receives the oil as the some leaves the still, and which is composed of a condensing coil from which the oil passes into one or more tanks. These tanks are closed, and

- they are provided with steam pipes extending down to difi'erent depths so that by letting steam into the oil on agitation is produced whereby the light parts are carried off and separated from the heavy parts, and at the some time the waste of a portion of the useful constituents of the oil is prevented. V

A represents a. condensing worm which is enclosed by the water jacket B. Through this worm passes the "1 While passing through the coil the oil is exposed to the action of steam which is introduced through one or more pipes a, branching off from the steam pipe I. The steam acting on the oil in the condensing coil chases the some ahead and causes the still to run freely. The tank (3 is provided with a. closely fitting cover, a, and the oil in the some is permitted to rise to about :1. level with the discharge spout of the coil A. On. discharging from this coil the oil is met by ajet of stccm which is introduced into the tank C, through c pipe, d, branching off from the steam pipe 12 and terminating opposite the discharge spout of the coil. Another pipe, o which also branches off from the steam pipe 5, extends down below the level of the oil in the tank 0, and the steam issuing from that pipe serves to agitate the oil in the tank. Said tank is situated in a waterjucket, D, through which a current of cold water passes so that the vapors, ,or a portion thereof, and the steam which enter the tool: are condensed. Those portions of the oily vapors, which do not condense in the tuck C pass through the pipe 0 into the tank '1, which is similar to the tank 0, and situated close to the some in the water jacket D. The liquid contents of the took 0, or, more properly speaking, the oil which accumulates in the some, is pumped over into the tank C, and on issuing from the @ipefit meets a. jet of steam which introduced through a pipe, 61, branching oil from the steam pipe 6. Another pipe, 1, which also branches off from said steam pipe, extends below the level of the oil in the tank 0, and the steam issuing from the same serves to agitate the contents of said tank. The water resulting from the condensation of the steam in the tanks 0 C is drown oh through the pipes g g, and these pipes form siphons, as shown in fig. 2, so to prevent the escape of gases from. the tanks. Suitable stopcocks in the several pipes s'crve to regulate the flow of tuo liquids and of the steam. The height of the liquid in the tank C C is observed by means of glass gauges 7L Ii, which are attached to the outside of the jacket- D and communicate with the tanks, as shown in figs. 2 and 3 of the drawing. By this treatment the light parts of the oil are completely separated from the heavy parts. The heavy parts collect in the lower portion of the tank C, and they pass off through the coil 2', the end of which extends through the end of tho jacket D and causes the liquid to discharge into the barrel or receiver E. The light ports of the oil which accumulate in the upper portion of the tank C escape through the pipe j into the tank C*, which is lower and of a difiercnt shape than the tanks 0 C, but which may be made similar to said tanks or in any other suitable form or shape. In this tank, which is also enclosed in the jacket D, sud surrounded by the cooling medium contained in said jacket, the light vapors are condensed, and the products resulting from this condensation are carried oil through thecoil k, the discharging end of which passes through the end wall of the jacket, and car-- ries the oil running from it into a barrel or receiver E, The gaseous parts which may still he mixed with the oil, as the some flows fi'om the tank C through the coil 2', swallowed to rise through the pipe Zwhich connects with the pip'oj, and such vapors which are still mixed with the oil as the some discharges from thecoilt'escape in the open atmosphere through the pipe m. A similar pipe, n, carries oh the uncondonsed vapors mixed with the oil escaping from the coil By this apparatus the distillation of petroleum oil and other liquids can be greatly facilitated, the flow of the stills being accelerated by the action-of the steam; and furthermore, by the steam acting on the vapors and liquid while the same are condensing or about to condense, a thorough separation of the oil takes place and noneof the heavy parts are allowed to escape with the light and nen-condensable vapors. The yield of oil is thereby increased and all danger arising from the explosive vapors is avoided, and furthermore by the action of the steam the oil is dcodorized and a pure white product is the result.

. What I claim as new, and desire to secure by Letters Patent, is-- 1. The arrangement of one or more steam jets a, in combination with the condensing coil A, constructed and operating substantially as and for the purpose set forth.

2. The steam jets cl or (1, applied in combination with tanks 0 or O, and with the pipes carrying the oil into said tanks, substantially as and for the purpose described.

3. Thejets 01* or 01, in combination with the tanks 0 or C, constructed and operating substantially as and for the purpose set forth.

i. The combination of the coil A, tanks C C 0*, steam jets a d d* cl d*, and coils in 2', all constructed 'itnd operating substantially as and for the purpose described. 7
